Hi Nick, Thank you for the kind words and congrats on quitting the smoke, I hear it's no good for you.

Now about your battery running low, because you have a Joytech eGo C upgrade battery here's a little trick I like to do. When the battery starts to run low click it over to the higher variable mode. It will give you a little more output and will also help in draining the battery faster so you can put it back on the charger. Below I listed the instruction on how to do that if you didn't get a manual.

Also we have few different cartomizers that have replacable heating coils as well as different resistance. The lower the resistance the higher the output. I have charts on the site that well explain that in more detail, do a search on the Vapor Den site for resistance vs voltages. I recommended the Kangertech T3 S, The heating element is on the bottom so the wicks always stay wet, you can replaceable the coils, an a lot simpler to troubleshoot. Come on down to the Den, so we can better assist you with this matter, and happy Vaping!

This Joyetech upgrade battery has two modes to switch. One is the constant voltage output mode which is what we have used before. Another is variable voltage output mode.

Switching operation and features :1. From constant voltage output mode to new battery voltage output: 1.1 When the mode is 3.3.v constant output mode, you can lock the battery by 5 clicks (blue LED blinks 3 times).1.2 By pressing button for 5 seconds, LED will change to orange with 3 blinks. The battery has switched to variable voltage output mode (battery voltage output mode). 1.3 Then you can use as usual by 5 clicks off and smoke in battery voltage output. 1.4 In new battery voltage output mode, the LED is orange and battery doesn't have power display function.1.5 When charging, orange LED will blink 5 times in this new mode.

2. From new battery voltage output to constant voltage output mode:2.1 In new battery voltage output mode, you can lock the battery by 5 clicks again (orange LED blinks 3 times).2.2 By pressing button for 5 seconds, LED will change to blue with 3 blinks. And the mode has switched to 3.3V constant voltage output mode. 2.3 Then you can use as usual by 5 clicks off and smoke in 3.3V constant voltage. 2.4 In 3.3V constant voltage, the battery features has no difference from present eGo-C battery.2.5 When charging, blue LED blinks 5 times in this mode.
